Good Day!!!

In this article, we are going to learn on How To Create User Login Logout Session Timeout Using PHP. This user login is a very common tutorial for us. In this case, we are going to add a function. In the user login, we set a session expiration time when the user logged-in. If the account of user elapsed to the set time then the user will no longer access his/her account and it will automatically log out after refreshing the page. HTML Source Code This HTML source code is to show the login form for the user.

<form method="post" action="">
<?php if($message!="") { ?>
<div id="message" class="blink_text"><?php echo $message; ?></div>
<?php } ?>
<table border="0" cellpadding="10" cellspacing="1" class="tblLogin">
<tr class="tableheader">
<td align="center" colspan="2">Login Details</td>
</tr>
<tr class="tablerow">
<td align="right">Username</td>
<td><input type="text" autofocus="autofocus" class="textbox_detail" name="user_name"></td>
</tr>
<tr class="tablerow">
<td align="right">Password</td>
<td><input type="password" autofocus="autofocus" class="textbox_detail" name="password"></td>
</tr>
<tr class="tableheader">
<td align="center" colspan="2"><input type="submit" class="btn_submit" name="submit" value="Login"></td>
</tr>
</table>
</form>

PHP Script This PHP script is used to check the session account of the user if the login session expiration time is reached.

<?php
session_start();
include("functions.php");
$message="";
if(count($_POST)>0) {
        if( $_POST["user_name"] == "admin" and $_POST["password"] == "admin") {
                $_SESSION["user_id"] = 1001;
                $_SESSION["user_name"] = $_POST["user_name"];
                $_SESSION['loggedin_time'] = time();  
        } else {
                $message = "Invalid Username or Password!";
        }
}
 
if(isset($_SESSION["user_id"])) {
        if(!isLoginSessionExpired()) {
                header("Location:home.php");
        } else {
                header("Location:logout.php?session_expired=1");
        }
}
 
if(isset($_GET["session_expired"])) {
        $message = "Session is Expired. Please Login Again.";
}
?>

Our tutorial look like this: This is the login form.
